The "removing watch on '/dev/sda'" is my fault. I added this rule:
KERNEL=="sda*", OPTIONS-="watch", to /etc/udev/rules.d/99-user.rules
, which I'm seeing it doesn't have the effect I wanted.

I'm running udevadm monitor right now, so if you need that information I
will mail it to you later. Thanks.
